DEVICE AND METHOD FOR PROCESSING METHOD EMBEDDED CONTENTS

摘要

PURPOSE: A device and a method for processing the method embedded contents are provided to effectively express the details and a characteristic of the contents by joining the method to support the characteristic and the use of each content with the metadata including the description, a use right, and a use rule for the contents. CONSTITUTION: A contents packager(10) packs up the contents, the metadata, and the method, and carries out the encryption and the electronic signature. A contents unpackager(20) unpacks the packed contents, examines the electronic signature, and carries out the decryption. A method manager(30) examines that the method is a normal code, and manages the method. A method execution environment part(40) guarantees the secure execution of the method by constructing an independent environment. An access controller(50) reads and analyzes the metadata, and makes only a certified module access the metadata by judging the certification of a software. A contents player(70) offers an access API(Application Program Interface) for the method, manages the certification information of the software module, and processes the contents by requesting the execution of the method and receiving a result.
